Description

Technical Field

[0001] The present invention and the technical field of automobile tire sponge application specifically relate to a continuous multi-stage silent sponge conveying and application device and an application method. Background Art

[0002] Tire noise is caused by the friction between the tires and the road when the vehicle is driving at high speed. The noise level depends on the road and vehicle conditions. The worse the road conditions, the louder the noise. In addition, there is a big difference between the noise level on asphalt roads and concrete roads. To solve this problem, silent sponges are often installed inside car tires for sound insulation.

[0003] At present, when sponge is pasted on the inner side of the tire, a conveyor belt is needed to transport the sponge. Since most existing conveyor belts are single-drive, the sponge is easily stuck during the transmission process. In addition, when sponge is pasted on the existing tire, the sponge is in the form of a long strip, and it is impossible to apply multiple sections of sponge to the inner side of the tire as needed.

[0017] A method for continuously delivering and applying a multi-stage silent sponge comprises the following steps:

[0018] Step 1: Linear transmission. When the sponge is laminated, it is transmitted by the machine and the sponge will be transferred to the transmission plate. During transmission, the driving machine works and the output end rotates, thereby driving the connecting shaft below to rotate. The connecting shaft drives the conveyor belt to rotate, and the conveyor belts on both sides rotate synchronously and cooperate with each other to transport the sponge to the rotating transmission mechanism.

[0019] Step 2: Rotational conveying. The sponge is conveyed to the conveying plate 2 through a linear conveying mechanism. When the sponge reaches the conveying plate 2, the coaxial rotating part on one side drives multiple conveying parts set on one side to perform curved rotational conveying. Then the sponge is transferred by the driving machine 2 and conveyed out again through the coaxial rotating part set at the end. During the conveying process, the conveying parts are located on both sides of the sponge, and the rollers on both sides cooperate with each other, so that the sponge can be conveyed by dual drive.

[0020] Step 3: Sponge bonding. After the sponge is rotated and conveyed, it will be attached to the inside of the tire. During the bonding, the telescopic feeding head at the second end of the conveyor plate works, the support frame is extended and retracted, and then the top roller 2 and the pressure wheel are driven to enter the inside of the tire sidewall to bond the sponge to the back of the tire tread.

[0021] Step 4: Sponge rolling. The pressure wheel is connected to the coaxial rotating part so that the speed of the second roller at the top matches the entire conveying track line. During the application process, it can not only be used to compact the sponge, but also match it according to the corresponding rotation speed of the tire, so as to achieve the effect of controllable relative speed deviation and accurate positioning between the tire and the sponge. The second roller at the top can be started as needed to accurately control the compaction position of each section / strip of sponge, thereby achieving the effect of precise positioning and compaction of multiple sections / segment of sponge.

[0022] The relative speed deviation between the tire and the sponge is controllable, so that the opening of each applied sponge can be 0-50mm different from the beginning to the end; the multi-segment / one-segment sponge can be completely closed, and further, the length of each sponge can be 0-20% larger than the beginning to the end. For example, if the inner center circumference of the tire is 2 meters, the total length of the one-segment / multi-segment sponge pressed in is 2 to 2.4 meters.

[0023] (III) Beneficial effects

[0024] The present invention has the following beneficial effects:

[0025] 1. This kind of continuous multi-stage silent sponge conveying and applying device, the sponge is located on one side of the conveying plate. During conveying, the coaxial rotating part drives the connecting rod on one side to rotate, and then drives the conveying part on one side to rotate to convey the sponge, drives multiple conveying parts arranged on one side to perform curved rotation and conveying, and then the guide rods on both sides of the conveying plate rotate, driving the outer roller to rotate synchronously, and the rollers on both sides convey the inner sponge at the same time, which can avoid the sponge from getting stuck. At the same time, after the conveying is completed, the pressure wheel mechanism at the front end can apply and roll the sponge.

[0026] 2. This type of continuous multi-segment silent sponge conveying and applying device places the cut multi-segment sponge into a linear transmission mechanism in sequence, and then adjusts the rotation speed of driving parts such as driving machine 1 and driving machine 2 according to needs, so that multiple segments of sponge can be transported and applied according to needs.

[0027] 3. During the application process, the frontmost roller 2 is connected to the rear drive motor, which can make the relative speed deviation between the tire and the sponge controllable and accurately positioned, and the top roller 2 can be started as needed to accurately control the pressing position of each section / each sponge, thereby achieving the effect of accurately positioning and pressing multiple sections / one section of sponge and controlling the amount of applied sponge.

[0049] Embodiment 2

[0050] like Fig. 9 A continuous multi-stage silent sponge delivery and application method comprises the following steps:

[0051] Step 1: Linear transmission. When the sponge is laminated, it is transmitted by the machine and the sponge will be transferred to the transmission plate 4. During transmission, the driving machine 2 works and the output end rotates, thereby driving the lower connecting shaft 18 to rotate. The connecting shaft 18 drives the conveyor belt 3 to rotate. The conveyor belts 3 on both sides rotate synchronously and cooperate with each other to transport the sponge to the rotating transmission mechanism.

[0052] Step 2: Rotational conveying. The sponge is conveyed to the conveying plate 2 5 through a linear conveying mechanism. When the sponge reaches the conveying plate 2 5, the coaxial rotating member 7 on one side drives multiple conveying members 10 arranged on one side to perform curved rotational conveying. Then the sponge is transferred by the driving machine 2 6 and conveyed out again through the coaxial rotating member 7 arranged at the end. During the conveying process, the conveying member 10 is located on both sides of the sponge, and the rollers 1007 on both sides cooperate with each other, so that the sponge can be conveyed by dual drive.

[0053] Step 3: sponge bonding. After the sponge is rotated and conveyed, it will be attached to the inner side of the tire. During the bonding, the telescopic feeding head located at the end of the conveying plate 2 5 works, the support frame 11 is extended and retracted, and then the top roller 2 13 and the pressure wheel 14 are driven to enter the inside of the tire sidewall to bond the sponge to the back of the tire tread.

[0054] Step 4: Sponge rolling. The pressing wheel 14 is connected to the coaxial rotating part 7 so that the speed of the top roller 13 matches the entire conveying track line. During the application process, it can not only be used to compact the sponge, but also can be matched according to the corresponding rotation speed of the tire, so as to achieve the effect of controllable relative speed deviation and accurate positioning between the tire and the sponge. The top roller 13 can be started as needed to accurately control the compaction position of each section / each sponge, thereby achieving the effect of precise positioning and compaction of multiple sections / one section of sponge.

[0055] The relative speed deviation between the tire and the sponge is controllable, so that the effect of 0-50mm opening difference between the beginning and the end of each sponge / each segment of the applied sponge can be achieved (the sponge is not completely closed within the inner circumference of the tire); the effect of complete closure of multiple segments / one-stage sponges (0mm difference between the beginning and the end) can also be achieved, and further, the effect of 0-20% interference between the end-to-end length of each sponge / each segment of the sponge can be achieved. For example, if the inner center circumference of the tire is 2 meters, the total length of the one-stage / multi-stage sponges pressed in is 2 meters to 2.4 meters.

[0056] Working principle: When applying the sponge, the sponge will be transferred to the conveying plate 4 through the machine transmission. During transmission, the driving machine 2 works and the output end rotates, thereby driving the lower connecting shaft 18 to rotate, and the connecting shaft 18 drives the conveyor belt 3 to rotate. The conveyor belts 3 on both sides rotate synchronously and cooperate with each other to transport the sponge to the rotating transmission mechanism.

[0057] During transmission, the working output end of the coaxial rotating member 7 located on one side rotates to drive the transmission shaft below to rotate. The rotation of the transmission shaft drives the outer bevel gear 1 to rotate. Since the bevel gear 1 and the bevel gear 2 are meshed with each other, the connecting rod 704 on one side can be driven to rotate, and then the conveying member 10 on one side is driven to rotate to convey the sponge, and multiple conveying members 10 set on one side are driven to perform curved rotation and transportation. Then the sponge will be transmitted by the driving machine 2 6 and conveyed out again through the coaxial rotating member 7 set at the end. During the transportation process, the conveying member 10 is located on both sides of the sponge, and the rollers 1007 on both sides cooperate with each other, so that the sponge can be dual-driven and transported. During transportation, the sponge is located on one side of the transmission plate 2 5, and then the guide rods 1006 on both sides of the transmission plate 2 5 rotate, driving the outer roller 1007 to rotate synchronously. The rollers 1007 on both sides simultaneously transport the inner sponge to avoid the sponge from getting stuck.

[0058] The sponge is conveyed and adhered to the inner side of the tire. During the application, the telescopic feeding head at the end of the conveying plate 2 5 works, the support frame 11 is extended and retracted, and then the roller 2 13 and the pressure wheel 14 at the top are driven to fit the sponge to press the sponge.

[0059] When sponges of different widths need to be transported, the position of roller 1007 can be adjusted. By adjusting the relative position of roller 1007, sponges of different widths can be applied.

[0060] When multiple sections of sponge need to be applied, the cut multiple sections of sponge are placed in the linear transmission mechanism in sequence, and then the rotation speeds of driving parts such as driving machine 1 2 and driving machine 2 6 are adjusted according to needs, so that the multiple sections of sponge can be transmitted and applied according to needs.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

During the lamination, the telescopic feeding head located at the end of the second conveying plate (5) works, the support frame (11) is extended and retracted, and then the second roller (13) and the pressure wheel (14) at the top are driven to enter the inner side of the tire to laminat the sponge to the back of the tire tread. Step 4: Sponge rolling, the pressing wheel (14) is connected to the coaxial rotating member (7), so that the speed of the second roller (13) at the top matches the entire conveying track line. During the application process, it can not only be used to press the sponge, but also can be matched according to the corresponding rotation speed of the tire, so as to achieve the effect of controllable relative speed deviation between the tire and the sponge and accurate positioning, and the second roller (13) at the top can be started as needed to accurately control the pressing position of each section / each sponge, so as to achieve the effect of accurate positioning and pressing of multiple sections / one section of sponge; The relative speed deviation between the tire and the sponge is controllable, so that each sponge / segment applied has an opening difference of 0-50mm at the beginning and the end, and the sponge is not completely closed within the inner circumference of the tire, or the sponge is completely closed within the inner circumference of the tire.
